2. A shock absorber for vehicles comprising a rigid member having doublediverging roller surfaces with the contracted portions adjacent eachother and connected by parallel roller surfaces, the said member beingmounted upon the vehicle frame, a leaf spring of substantially U-shapemounted upon the said vehicle axle-and having a transverse slot in thetwo arms in which the said rigid member moves, eyes on the end of thetwo pair of arms thus formed, a pin held in said eyes and having aroller pivotally mounted thereon within the said transverse slot, theSaid rollers being adapted to contact with the opposite faces of saidrigid member, so that movement l between said frame and said axle ineither direction is resisted by the forcing apart of said spring arm asthe rollers move along the said diverging surfaces.

In testimony whereof I aix my signature in presence of two witnesses.
